Although Apple gadgets are famous for their reliability, even with them failures occur. Therefore, it is not always possible to synchronize the iPad.

Why do we synchronize data? So that they are available on every device and are updated when new data appears. There are many reasons that prevent synchronization. Synchronization can be configured between gadgets, a computer, and the iTunes program. Sometimes it is not possible to make the settings, there are several reasons.

During the next iPad sync I encountered a problem with my computer that would frighten an untrained iPad user. The message sounded like this: iPad ( iPad name) failed to sync because the sync session could not be started. If you have an iPhone, then the message will be about the iPhone.

Let's write down the steps you need to take so that this message disappears and you can synchronize normally.

1. Check availability iTunes updates. On the menu iTunes->Updates. If there is new version iTunes, then install it.

3. Restart your iPad. How to restart iPad. If your iPad is locked with a passcode, unlock it.

As a rule, these three steps are more than enough to ensure that the error does not appear again and you synchronize normally.

But if the problem remains, you can use these other methods and tips:

1. If your backups add up to external hard disk, check if it is accessible. For example, my media library is stored on a separate hard drive and backups are stored there, but this hard drive tends to fall asleep to save energy.

2. Check your time and date settings on your computer and iPad (iPhone, iPod). You must have the same time and the same time zone set. On iPad go to Settings->General->Date and time.

3. Tip for Windows only:

a) close iTunes

b) run the command line as an administrator (START -> All Programs -> Accessories. Right-click on “ command line"(or CMD) -> "Run as administrator").

c) enter the command “netsh winsock reset" Launch it. This program resets the winsock protocol settings. From what I was able to google, it became clear that this was necessary after the consequences of the intervention of some viruses or Trojans. So we additionally recommend checking the system with an antivirus.

d) restart your computer and try synchronization again.

4. Go to iTunes settings. In the “Devices” section, check the “Prohibit automatic synchronization iPod, iPhone, iPad devices." Connect your device to your computer and try synchronizing.
